Endy vs. Casper Mattress Review

It’s that time again…time for another mattress battle! In today’s contest we’re pitting the titan of the online mattress world, Casper vs. rapidly growing Canadian challenger, Endy.

Casper is one of the most popular online mattresses in the US, with such an incredible marketing budget that you can hardly ride the subway, listen to a podcast, or browse the web without seeing their ads. Endy is a Canadian company aimed at providing a great value foam mattress that meets the needs of both their US and Canadian customers.

Construction

The Endy mattress is a 10″ mattress built from 3 different layers of foam.

Top layer (comfort) – 2″ layer of gel-infused memory foam. This layer provides the initial comfort and feel for the mattress. Additionally, the gel infusion is designed to dissipate heat, helping to maintain a cooler sleeping surface. It has a density of 3.0 PCF (pounds per cubic foot).

Middle layer (transitional support) – 3″ layer of transition poly foam. The middle layer is designed to act as a transitional layer between the top comfort foam and more supportive base layer. It has a density of 1.8 PCF.

Bottom layer (support + foundation) – 5″ layer of support foam. This layer acts primarily as the foundational base for the mattress. It also provides a level of deep compression support for sleepers. It has a density of 1.8 PCF.

Cover

Built from a quilted polyester fabric, the cover of the Endy mattress is both soft and durable. The grey side panels contain a sturdier build than the top piece of fabric. That said, the top still feels durable enough to take some hits without damaging. In addition, the quilting used within the cover adds a degree of thickness to the overall build, which gives it that slightly thicker feel.

When looking at the aesthetics of the cover, Endy did a nice job. Although they have adopted what has become somewhat of the staple design for many online mattress companies today, it is still very well done. Smooth transitions from white to grey and a quilted diamond pattern on top all come together for a nice appeal overall. The cover is also removable and can be spot cleaned.

Firmness, Feel, & Support

The firmness of the Endy mattressis a little different than most mattresses I’ve tested. The Endy has one model that ranges from 6-7.5 out of 10 on the firmness scale, where 10 is the most firm. Typically, mattress companies tend to make a few different models with varying firmness levels, or just one mattress that nails a specific feel. The construction of the Endy creates a wider range with respect to the firmness and feel, varying by weight of the sleeper.

Endy firmness – 6-7.5 out of 10, where 10 is the most firm

At 140 pounds, I was finding the Endy to have a slightly firm feel. I place it at a 7 out of 10 on the firmness scale. That said, this is not the case for everyone. As sleepers get into more of a middle of the road weight class (150-200 pounds) the mattress is going to feel more like a 6.5 out of 10. Once sleepers get over the 200 pound mark, the Endy is going to fall closer to a 6 out of 10.

Therefore, the feel of this mattress can be directly correlated to the weight of the sleeper. The heavier you are, the softer it feels (to a point), and vice versa.

Going hand-in-hand with the firmness, sinkage depth. During my sleep test I was only seeing about 1″ of sinkage while lying normally on my back. This low level of sinkage means very little amounts of hug and contour around your body. By floating more on top of the mattress, the firmer feel becomes even more prominent. Bear in mind, your sinkage results will vary based on weight and body type.

Although the Endy does offer a slightly firmer feel for lighter sleepers and a medium to medium firm feel for heavier sleepers, I would not take anything away from the mattress in terms of support. That said, you will want to be 100% sure the firmness and feel dynamic (based on your weight class) is appropriate to your needs and desires.

Personally, I tend to prefer more of a medium feel. Thus, the Endy created some uncomfortable pressure points in my lower back. Back, stomach, and heavier side sleepers will benefit most from this mattress.

One of my favorite characteristics about the Endy mattress is its edge support. As an all foam mattress it was quite impressive to see the edges hold up the way they did. The slightly firmer design does play a role in this factor. Whether you’re sitting or sleeping on the edges, the Endy’s performance is a step above most foam mattresses I have tested to date.

Finally, cooling. Due to more of a floating feel, sleepers are less likely to encounter heat build up around their body. In addition, the gel-infused memory foam does a good job of absorbing and dispersing heat throughout the mattress.

Construction

The Casper mattress is a 9.5″ mattress built from 4 layers of foam.

Top layer (comfort + cooling) -1.5″ of synthetic Dunlop latex foam. The latex is designed to provide good bounce, cooling, and comfort for the mattress. The latex is placed on top of the layer of memory foam in order to prevent any heat retention issues with the memory foam. It has a density of 3.3 PCF.

Second layer (support + pressure relief) – 1.5″ of memory foam. This layer of memory foams adds a nice degree of contour, hug, and support for sleepers. It has a density of 4.0 PCF.

Third layer (transitional support) – 1.5″ of poly foam (non-visco elastic). This layer acts as a transitional foam support layer, helping to ease sleepers from the top comfort layers into the support foam. It has a density of 2.5 PCF.

Bottom layer (foundational support) – 5″ of high-density support foam. This layer acts as the foundational base for the mattress, providing support and deep compression support for sleepers. It has a density of 1.8 PCF.

Cover

The cover of the Casper mattress is similar to the Endy in that is also uses the two-tone, grey and white design. The top portion of the cover is made from 100% polyester and is quite porous. As a thinner cover with a porous design, the foams are able to breathe easier. The side panels used on the cover are a polyester and polypropylene blend and offer better durability than the top piece of fabric.

Firmness, Feel, & Support

The Casper mattress lands at a 6 out of 10 on the firmness scale, where 10 is the most firm. At this firmness level, Casper is considered a medium firm mattress.

Although Casper does feel like a 6 out of 10 for a majority of sleepers, the feel will change as body weight increases. For heavier sleepers, the Casper is going to feel more like a 7 out of 10. This is due to the increased level of sinkage, which puts them in closer contact with the harder and less comfortable transition and base poly foams.

Casper firmness – 6-7 out of 10 on the firmness scale (10 being the most firm)

At 140 pounds, I was seeing a rather pronounced level of hug from the Casper mattress. While lying normally on my back I saw about 2″ of sinkage, yet in no way did I feel stuck in the mattress. This is directly correlated to the top layer of latex used in the Casper. By placing a latex layer on top of memory foam the mattress has the ability to avoid that stuck feeling that more traditional memory foam mattresses often create. While the support of the Casper is middle of the road, the top layer of latex does offer good bounce and response.
